Spring is coming!

The bubble-wrap insulation on the greenhouse walls worked like a charm! Propane consumptions was drastically cut. Last year I had to refill the propane tank 4 times; this year it is still running on the first tank from November, and looks as though it will make it through the next few weeks into real spring weather without having to refill. What a coup! The cost of the bubble insulation was recovered in a single season!
